IMPROVEMENT IN LINKS.

Specification fo'ming part of Letters Patint No.15 1,7 lS, dated June 9, 1874; application led May 8, 1874.

To all 'whom fit may concern:

Be it known that I, ROBERT C. SOHENCK, Jr., of Dayton, county ot' Montgomery and V State of Ohio, have invented certain Improvements in Links, of which the following is a specification My invention relates to links, made of iron or other suitable metal, for coupling together railroad vehicles, or to be used in the construction of chain-cables; and consists in the forma- Atin of cords or utings upon the surface of the metal of the link, so as to give to the same greater elasticity and lightness than the links nonr in use possess, without additional expense.

In the accompanying drawings, Figure l exhibits the link as seen from above. Fig. 2 exhibits a cross-section of the link.

The cords or ilntin gs are seen in both figures,

face with the same diameter, and thus greater strength with less Weight, than in the ordinary link. rEhe link is as `much'lighter than one made in the ordinary way as the weight of the metal removed from between the cords, While the saving in metal will more than pay the small extra cost of manufacture. As a net result I obtain a link of much 'greater strength, less Weight, and cheaper than the links now 1n use.

The cords may be formed in the metal of which the link is constructed by the ordinary process of rolling. The number and size of the cords may be varied according to the use to which the link is to be applied', or the convenience of the manufacturer.

As the ends ofthe links are less exposed to severe strains than the sides, it is only material to my invention that the metal forming the sides of the links be fluted. The ends may or may not be uted, as preferred.

W'hat I claim as lily-invention is- A link having itssurfacefluted, for the purpose of giving greater strength and elasticity to the link, substantially asfdescribed.
